Spring Security - Expression-Based Access Control with @PreAuthorize

[Updated: Sep 11, 2017, Created: Sep 11, 2017]

Spring Security provides the ability to use Spring EL expressions as an authorization mechanism. We can use @PreAuthorize annotation and can specify method access-control expression as its attribute.

There are four annotations which support expression attributes to allow pre and post-invocation authorization checks around methods: @PreAuthorize, @PreFilter, @PostAuthorize and @PostFilter.

@PreFilter and @PostFilter annotations support filtering of submitted collection arguments or return values.

Following example shows the use of @PreAuthorize.


We are going to reuse our @Secured annotation example. We just need to replace @Secured with @PreAuthorize annotation in the service class and enabled pre/post annotations in Java config class via prePostEnabled = true .

Service Interface

package com.logicbig.example;

import org.springframework.security.access.prepost.PreAuthorize;

import java.util.List;

public interface ShoppingCartService {
  int placeOrder(OrderItem order);

  List<OrderItem> getOrderList();

Here is a list of the expressions which can be used with the pre/post annotations.

Java Config class

@EnableGlobalMethodSecurity(prePostEnabled = true)
public class AppConfig extends WebSecurityConfigurerAdapter {

To try examples, run embedded tomcat (configured in pom.xml of example project below):

mvn tomcat7:run-war

The output will be same as this example.
